[Wernicke's encephalopathy following sleeve gastrectomy for morbid obesity]
1Service de neurologie, CHU de Pointe-à-Pître, route de Chauvel, 97139 Guadeloupe, France.
Introduction:
Bariatric restrictive interventions, as sleeve gastrectomy or gastric banding can cause metabolic complications, especially when vomiting is present, such as thiamine deficiency that can lead to Wernicke's encephalopathy.
Case Report:
A 31-year-old man with a 47kg/m(2) body mass index presented with Wernicke's encephalopathy, with ophtalmoplegia, nystagmus, ataxia and confusion, followed by a Korsakoff syndrome, occurring two months after a sleeve gastrectomy. MRI showed hyperintense signals on T2 and FLAIR image in both thalamus, periaqueducal area and mamillary bodies.
Conclusion:
A close clinical and biological monitoring is required in the first year after surgery, especially if vomiting occurs. Early diagnostic and treatment are needed to avoid severe sequelae.
